Subject: [PATCH 4.0 26/72] MIPS: Kconfig: Disable SMP/CPS for 64-bit

4.0-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Markos Chandras <markos.chandras@...tec.com>

Commit 6ca716f2e5571d25a3899c6c5c91ff72ea6d6f5e upstream.

A 64-bit build for Malta produces far too many build problems
when SMP/CPS is selected. Moreover, there is currently no 64-bit
product with SMP/CPS so we disable SMP/CPS when building for
64-bit until it is properly supported.
